Display Business Division’s FMM is a metal sheet used to deposit sub-pixels that emit 3 types of light, RED/GREEN/BLUE, in the OLED display manufacturing process, and is key for the OLED displays technology.

Form and Function of the Material

The FMM is a thin metal sheet with tiny openings which induce organic materials, which are the OLED emitters, to be deposited at designated areas on the substrate during the OLED panel manufacturing.

• Form of materials
  • Numerous high-precision/high-fine holes are distributed on the surface of the FMM to ensure that RGB organic materials can pass through.

• Function of materials
  • The FMM is used to ensure that red (RED), green (GREEN), and blue (BLUE) organic materials can be deposited at designated areas on the substrate.

디스플레이소재의 특장점을 항목에 따라 에칭방식, 전주 도금 방식(한화이센셜), 비고로 나누어 설명합니다.

Items	Hanwha e-ssential FMM	Remarks
Stick thickness	Ultra slim thickness of less than 10um can be secured (Available for a high resolution of over 1,000ppi)	The thinner the stick, the higher the resolution.
Opening shape	Easy to implement polygons with patterning technology	Maximization of opening ratio by forming accurate polygonal patterns: advantage for Lifetime, efficiency of OLED display
Taper shape	No step height occurs by patterning technology	There is No step-height, and hence, the designated entire areas can be effectively deposited.
